Please look for bad caps as shown in my pictures:
http://s807.photobucket.com/albums/yy352/budm/HP%201702/

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Just press your finger anywhere on the screen and it will turn darker around that spot.

My monitor hp 1702 is saying monitor is going to sleep. I cant even get my cd part to open windows xp professional 1-2 cpu hp


It sounds like you have the problem with the PC itself, you can try this monitor with another PC just to narrow down the problem.
The PC mayhave hardware problem usch as bad power supply that may explain why you cannot even open the CD tray.

When turn monitor on it says going to sleep


It says no Signal right? check your connections, if the computer has a graphics card it may have failed and you need to plug the monitor into the regular monitor output.

HP L1702 lcd monitor power on then goes off


There are 8 caps that need to be replaced on these monitors.

It is an easy repair if you know how to do it. If not, then your local TV repair man can do it fairly cheaply and quickly.
